Chapter 1059

Before the words were heard, the head of the headquarters immediately turned back and said with a slightly excited look: "the conformal fuel tank on the Zhenlong verification machine is in that position, that is to say Strong 5h.... "

"We are still sorting out the report of Qiang 5h. Hongtong factory is summarizing it. It is expected that it will be reported next month." Before the head of the headquarters had finished speaking, Zhuang Jianye reported truthfully.

The head of the headquarters waved his hand: "don't wait for next month. Since I've come here, I'll go and have a look myself."

Compared with the UAE and Algeria, the head of the headquarters is obviously more concerned about the strong 5h.

It's no wonder that small money can still be earned without it, but strong 5h is a real equipment that can quickly improve the combat effectiveness of the army and has excellent cost performance.

Especially in the face of the military struggle along the southeast coast, with the current reality of the Chinese air force and naval aviation, once the strong 5h equipment is put into service, it can not only quickly form combat capability, but also improve the air force and naval aviation's ground attack capability, and even the precision attack capability of key targets.

It can be said that it is the key improvement model planned by the aviation force in the past two years.

At the end of 1996, the project was set up for bidding. Several aviation manufacturers and R & D units including Tengfei group, Hongtong factory, Chenggong group, northeast Aviation Manufacturing Co., Ltd. and Binjiang factory participated in the bidding.

As always, Tengfei group has become a company runner, and the first round has been brushed down. The reason is also very simple. The improvement plan given by Tengfei group is too advanced and the cost is too large, so it was directly given to pass.

Zhuang Jianye is neither angry nor angry about this. After all, Tengfei group, which lacks experience in the development of combat aircraft, is here to brush up its experience this time. What's more, Hongtong factory, the old owner of strong 5 attack aircraft, is also involved in the bidding, so it never thought that the bidding would be successful.

But even so, Tengfei group is not as completely isolated from strong 5h as others think.

On the contrary, as one of the dual cores of Tengfei Chengdu system, Tengfei group, in the aviation industry alliance formed by Tengfei group, northwest aviation factory, Chenggong group and Hongtong factory, although it is not good at the complete machine development of military combat aircraft, it is one of the most important supporting components in the whole system.

Among other things, aeroengine is a military combat aircraft.

In addition, jsnb-ii aviation and aerospace comprehensive analysis system is also an advanced analysis software that cannot be avoided in the development process of military combat aircraft.

If you add in several modern wind farms invested by Tengfei group in cotton in recent years, although there are no military combat aircraft of Tengfei brand on the market, there are legends of taking off in the field of domestic military combat aircraft in recent years.

Therefore, although Tengfei group was swept down in the first round, Hongtong factory, which successfully won the bid, found Tengfei group immediately after receiving the bid, and signed the supply and marketing contract for the leasing of aero-engine, jsnb-ii aviation and aerospace comprehensive analysis system, strong 5h wind tunnel test and the production of other important spare parts.

Therefore, Tengfei group is not generally involved in the strong 5h project, but as a joint research and development unit.

Other people don't know about these things, but the head of the headquarters is very clear. Theoretically, the progress of the strong 5h project should be reported by Hongtong factory. Tengfei group is only responsible for writing the part it undertakes. However, the head of the headquarters knows that many of the parts undertaken by Tengfei group involve the whole, and even some parts are still the core. So when he learns that the strong 5h project has made progress, Can't wait to see, this Navy and air force urgently need to connect to the ground small expert exactly where step.

"What is the effect of the static test of the whole aircraft?"

"I found some small problems, but they were all corrected in time."

"When is the test flight expected?"

"If the expert group of Hongtong is on a fast track, it will be able to test fly before the end of the year."

"Has the relevant production organization started?"

"Yes..."

……

On the way to the Qiang 5h static test site, the head of the headquarters said more than he had received Abdullah and Mahmoud together before. Fortunately, Zhuang Jianye has always been very attentive to the Qiang 5h, so he can be regarded as a flow of answers. In this way, the car went all the way, about 20 minutes, and then came to the second aircraft manufacturing plant of Tengfei group in Xingzhou.

After entering the factory, a group of people first had a light meal in the canteen, and then hurried to the static test workshop. As soon as they entered the factory, they were attracted by the strong 5h which was being hung in the commissioning.

There is no painting on the whole qiang5h. It looks yellow and green as if it is pasted with plasters one by one. However, experts know that these ugly plasters are actually high strength aluminum lithium alloy. This material is not only lighter than traditional aluminum alloy, but also has better strength. What's more, the cost is much lower than titanium alloy.

It's a good material for the model with outstanding cost performance.

Thanks to the application of aluminum lithium alloy, the weight of the strong 5h model is reduced by 12.7% and the structural strength is increased by 8.6% compared with the previous strong 5 model. The advantage of this is that the strong 5h has a larger missile carrying capacity and a longer range.Of course, if you want to achieve this goal, you can't do without a good aero-engine.

For this reason, Qiang 5h got rid of the shackles of Wuye's ever-changing and turbojet 6's self-improvement, and completely abandoned turbojet 6 and chose wd-42s turbofan engine produced by Tengfei group.

The overall dimension is equivalent to that of vortex jet 6.

Taking the afterburner into account, the total length of the afterburner is 5400 mm

and the diameter is 650 mm

thanks to the advanced materials and technology, the wd-42s turbofan engine is 50 kg less than that of the turbojet 6, which is 658 kg.

The thrust is about 20% higher than that of vortex jet-6, which makes the intermediate thrust 3.1 tons.

The afterburner thrust reaches 4.2 tons.

As for the fuel consumption, let alone the conservative estimation, the fuel consumption is 30% lower than that of vortex jet 6.

The most direct result is that the strong 5h flight quality and payload are greatly optimized.

Regardless of flight quality, the payload alone, in the past, strong 5 could carry up to 1.5 tons of ammunition and carry out ground attack missions with a radius of 400 to 600 km.

The improved strong 5h can carry 3.8 tons of ammunition and carry out the ground strike mission with a radius of more than 1200 km.

In addition to the weight reduction of the airframe structure and the powerful aeroengine, the main reason for such a big improvement is that the fuel capacity of the strong 5h is 25% more than that of the previous model.

Because Tengfei group has designed an integral conformal fuel tank at the waist of the strong 5h bee, starting from the rear of the cockpit, slightly uplifted along the north of the fuselage in streamline form, and then extended to the front section of the vertical tail along both sides of the fuselage like flying shears.

The thickness is not big and the length is just right. The most important thing is that it has a high degree of integration with the body. If you don't identify it carefully, you can't see that the conformal fuel tank on the strong 5h is actually an external matching component.

The head of the headquarters and others all nodded with satisfaction when they saw this scene. Then they looked down at the wing of the pylon being tested. Then the head of the headquarters squinted slightly, staring at the ammunition on a pylon: "this is Laser guided bomb... "
